PC woken by strange device

5 posts in this topic

My PC just woke and powercfg /lastwake shows

Wake History Count - 1
Wake History [0]
Wake Source Count - 1
Wake Source [0]
Type: Device
Instance Path: PCI\VEN_1022&DEV_9608&SUBSYS_96011849&REV_00\3&267a616a&0&48
Friendly Name:
Description: PCI standard PCI-to-PCI bridge
Manufacturer: (Standard system devices)

which is apparently an AMD device.

Does anyone know why this would wake my PC, as I obviously don't want it waking randomly for no good reason?

Well it is part of the Chipset drivers, but not sure what exactly it is.

Yeah, it seems strange as I'd expect the NIC or my PCI TV tuner to be able to wake it but I think they're normally properly identified by lastwake, as is the mouse or keyboard (or at least it says USB device), so I'm not sure what this could have been.

Have you checked the Task Scheduler to see if anything was run at the time of the wakeup?

That probably would have been a good idea at the time but I don't have a note of what time it happened unfortunately.

It's mostly only Windows tasks in there anyway, except for Avast! Emergency Update, Comodo Update and GoogleUpdateTasks but I've disabled the latter anyway and they last ran on 26/08. None have "Wake the computer to run this task" enabled anyway.

The only task I can see that ran anywhere near the time before I started this thread is Comodo Update at 20:35 but as I say, that's not set to wake the computer.
